The patch defines PCI error types and functions in eeh.h and
exports function eeh_pe_inject_err(), which will be called by
VFIO driver to inject the specified PCI error to the indicated
PE for testing purpose.

The patch adds one more EEH sub-command (VFIO_EEH_PE_INJECT_ERR)
to inject the specified EEH error, which is represented by
(struct vfio_eeh_pe_err), to the indicated PE for testing purpose.

This will need to be updated if vfio_eeh_pe_op ever gets updated again,
why not just use offsetofend() now and avoid that future hassle and
breakage.

Good point. I'll update to use "minsz = offsetofend(struct vfio_eeh_pe_op, err.mask)",
then use "minsz" for the parameter check and memory copy.
